, t 2 Claims.

This invention relates to paper fasteners of the type composed of onlytwo parts, relatively, a base having narrowed end extensions, and theother a ,compressor provided with openings receptive of the extensions.

One of the objects is to provide a fastener sim- ;ple and inexpensive tomanufacture, easily applied or removed, and capable of extension toaccommodate widely varying thicknesses of paper assemblages.

A further feature is in the provision or 9. ms-

itener thatis actually looked when in operative position, and cannotdamage the finest of papers, the parts of the fastener being preferablymade of non-corrodable material; i

Another purpose is to produce a paper fastener of relatively light, thinsubstance, stiffened and Y rendered substantially inflexible by reasonof .-a j plurality of parallel indentations embossed on the surface.

These and other advantageous objects are at,-

tamed b the novel construction, combination element, and

Figures 4 and 5 are perspective views of these elements, shown inposition for cooperative attachment. i Referring to the drawing, thenumeral I0 indicates broadly the base of the fastener, composed of abody portion I I having spaced flexible prongs or tongues 12 capable ofbeing readily bent at applied to right angles to the body so as to pasthrough openings l3 in the bundle of papers.

The body portion, and tongues are preferably heavily embossedlongitudinally at and 15 to increase the strength thereof and impartrigidity to the, same.

,The compressoror protector plate 16 is composed of preferably anelongated rectangular, relatively flat plate, provided at each endthereof with a pair of angular and upwardly extending prongs l1 and I8,projecting in the direction towards the adjacent end of the Plate.

These prongs are struck out of the plate, thereby producing openings I 9and 2|! which are adapted to receive the longitudinally embossed tongues12 of the base 10.

The upwardly angular extending prongs H, which are preferably locatednearest the end of the plate l6, are provided with serrated edges 2 I,corresponding with the serrations in the openings I9 in the plate fromwhich the prongs H were formed. t

The compressor plate I6 is also embossed longitudinally at 2| and 22 toincrease the strength thereof and impart rigidity to the same.

The base In and the compressor plate I6 may be formed of any suitablematerial which lends itself well to manufacture, as for instance,Celluloid, pressboard, fibre, fabric or thelike.

In practice, the flexible prongs l2, of the base H], are projectedthrough the openings l3 in the papers; on the side of the latter,normally forming the top, i placed the compressor plate Ill.

The ends of the prongs l2 are passed through the serrated openings l9and I9, turned outwardly I over the tops of the serrated prongs I1 andH, and over the plate l6 and then the ends of the prongs are passedthrough the openings 20 and 20 and under the angular prongs I8 and plate[6. Thus, theprongs are temporarily locked in position, but can beraised for the insertion or removal of papers.

It is to be noted that the prongs are covered by other parts of thedevice, and that no projections extend to interfere with the relativelysmooth surfaces of the entire fastener.

The foregoing disclosure is to be regarded as dscriptive andillustrative only, and not as restrictive or limitative of theinvention, of which, obviously, embodiments may be constructed,including man modifications, without departing from the spirit and scopeof the invention herein set forth and denoted in the appended claims.

Having thus fully described the invention and set forth the manner ofits construction andapplication, what is claimed as new and sought to besecured by Letters Patent, is:

1. A fastener comprising a compressor plate having a pair of ends, apairof adjacent, angularly directed, parallel, upwardly extending prongsadjacent each end of said plate, said prongs being struck out of thematerialof said plate to define openings in the plate adjacent saidprongs, each pair of prongs being directed toward the adjacent end ofthe plate, serrated edges on that pron of each pair which is nearest theadjacentend of the plate, and a fastener base provided with a pair oftongue portions, each, tongue portion being adapted to be passedupwardly plate to define openings in the plate adjacent said 5 prongs,eachpair of prongs being directed toward the adjacent end of the plate,and a fastener base provided with a pair of tongue portions, each tongueportion being adapted to be passed upwardly through the opening fromwhich one prong was struck, and to be bent over said prong anddownwardly under the adjacent prong and through the opening from whichthe said lastnientioned prong was struck.
